Description
Technical Field
The invention relates to the field of intelligent automobiles, in particular to a roof for protecting a human-ground collision damage in a high-speed collision accident of an intelligent automobile.
Background
Unlike vehicle occupants, pedestrians are often more seriously injured in traffic accidents, and thus it is particularly necessary to protect pedestrians. Human injury in a traffic accident results from a first impact of a vehicle followed by a second impact with the ground. According to the prior research results, the injury to human body in high-speed collision accident mainly comes from vehicle collision, but the ground injury is not negligible. The fatality rate of pedestrians in high-speed accidents is not 100%, particularly along with popularization and application of vehicle-mounted safety equipment such as pedestrian protection airbags and the like, the fatality rate caused by vehicles is lower, and at the moment, ground damage protection is more necessary. Especially, when the human body is seriously impacted by the vehicle body, the capability of protecting the human body structure is reduced, and the collision between good people can be protected at the moment, so that the vehicle has great value.
In the prior art, people pay more attention to the scheme for reducing the collision damage of people and vehicles, but the research on the method for protecting the collision damage of people and vehicles is not much, and only a few documents or patents mention that a safety air bag is arranged at the vehicle head to prevent a human body from falling to the ground or a viscous vehicle head is designed to stick the human body to the vehicle head after the collision of people and vehicles occurs. These methods are not feasible, but the human body will get a greater velocity obliquely upwards under high speed impacts, which can reduce the harm to the human body during the protection process if the human body and the vehicle are allowed to separate for a while.
The accident that the height of the human body thrown out of the car roof can be higher than the car roof is defined as a high-speed collision accident. In this type of accident, the flying height of the human body will be higher than the vehicle roof after being thrown out. For the intelligent automobile, the intelligent automobile has the full capability of monitoring and tracking the position of a human body in real time and realizing the protection of human-ground collision by moving the automobile so as to keep the human body and the roof to be connected with the automobile roof and prevent the human body from falling to the ground after the human body is higher than the roof and the automobile runs forwards at the same speed for a period of time.
In order to achieve the purpose of using the vehicle roof to receive the human body and further protect the human and ground collision, it is necessary to design a vehicle roof meeting the requirements. The intelligent automobile roof for protecting the human-ground collision damage in the high-speed collision accident needs to have certain capability of protecting the human body in the process of catching the human body firstly, and then has the capability of preventing the human body from falling to the ground secondly. The related results are almost blank throughout various research literatures.

The air bag layer after being unfolded consists of 3 parts of an air bag, an air column on the surface of the air bag and an air column head.
Preferably, the air bag in the air bag layer of the roof, which is used for protecting the roof from human and collision damage in a high-speed collision accident, of the intelligent automobile is in a cuboid shape after being detonated, the length and the width of the air bag are consistent with those of the roof, the heights of the air bag layer and the roof are fixed values, the lower surface of the cuboid is connected with the roof support layer, and the upper surface of the cuboid is full of air columns. The function of the air bag and the air column is 2: one is to protect the human body in the process of receiving people; and secondly, the resistance of the human body sliding on the car roof is increased through the air columns so as to prevent the human body from moving in the horizontal plane of the car roof.
Preferably, an air bag surface air column in an air bag layer of a roof of an intelligent automobile for protecting human collision damage in a high-speed collision accident is cylindrical after detonation, the height of the air column is higher than 0.5 m, and the lower end of the air column is connected with the air bag. In the process of protecting pedestrians, the air column and the air bag are detonated simultaneously and are unfolded together. The main functions of the gas column are 3: one is to protect the human body in the process of receiving people; secondly, the resistance of the car roof is increased to slow down the sliding of the human body; thirdly, the air column is used for providing a hand-grasping object for the human body which is not injured by the fate so as to consume the kinetic energy of the human body and prevent the human body from sliding downwards.

The gas column head after detonation is tightly connected between the adjacent spheres under the action of glue, so that the human body is prevented from moving on a horizontal plane while the human body is prevented from rebounding, and the purpose of preventing the human body from falling to the ground is achieved.
Preferably, the roof for protecting the human body from collision damage in the high-speed collision accident of the intelligent automobile comprises the following steps: when the intelligent automobile monitors that the throwing height of the human body can be higher than the roof in a human-vehicle collision accident, the air bag and the air column in the air bag layer are detonated, and the vehicle motion is controlled so that the human body and the vehicle can move forwards at the same speed until the human body falls into the middle of the roof after the throwing height of the human body is higher than the roof. When the human body is detected to contact the middle part of the car roof, the air column heads in the air bag layer are detonated and the car body starts to be slowly braked until the car is completely static. Through the control of the vehicle motion in the first step, the speed difference between the human body and the vehicle is small, so that the relative speed between the human body falling to the vehicle roof and the vehicle roof is low. After the air column heads are exploded in the second step, the air column heads which are not compacted by the human body are mutually adhered, so that the movement of the human body in the plane of the roof is powerfully prevented while the human body is prevented from rebounding. The purpose of fixing the human body on the roof is realized by means of the two steps, so that human and ground collision is isolated.
